Description

Technical Field

[0001] The utility model relates to the technical field of boiler circulation systems, in particular to an electrode boiler circulation system. Background Art

[0002] Electrode boiler is a technology that utilizes the high thermal resistance of water to directly convert electrical energy into thermal energy and generate steam. During the use of electrode boiler, desalted water is mainly used for steam burning. After steam is generated, water evaporates and the water can be circulated. However, the electrolyte added to the water will not evaporate with the water. It will be adsorbed to the electrode along with the current, causing a decrease in electrolyte in the water and affecting the conductivity of the water. Therefore, electrolyte needs to be supplemented. The circulation system of existing electrode boilers usually uses an external tank to supplement electrolyte. However, when adding electrolyte, it is mainly added at one end, which can easily cause the electrolyte to fail to be integrated into the water in time, resulting in a decrease in local conductivity efficiency and affecting the operation of the boiler. In view of this, in-depth research was conducted on the above-mentioned issues, resulting in this case. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides an implementation scheme: in order to solve the problem that the electrolyte concentration of the electrode boiler decreases with the evaporation of water vapor during use, the electrolyte needs to be supplemented. The existing electrolyte supplement device mainly relies on a pump to pump electrolyte water from one side of the boiler, and the electrolyte cannot be dissolved in the water in time, resulting in a decrease in local conductive efficiency, affecting the operation effect of the boiler. Specifically, the application uses an electrode boiler circulation system, and a uniform material feeding structure is arranged inside the boiler so that the electrolyte can be quickly dissolved in the water. The equipment is based on a boiler shell 1, which is a vertical cavity closed shell. There are at least one set of heating electrodes 2 extending from the boiler shell 1 to the inside of the boiler shell 1. By energizing the heating electrodes 2, the water in the boiler shell 1 is heated, and the electrical energy is converted into thermal energy. A ring-shaped feeding pipe 3 is arranged on the top of the boiler shell 1 as a passage for supplementing the electrolyte.

[0019] According to the instruction manual Figure 1-3 It can be seen that a feed pipe 4 extends from one side of the annular feeding pipe 3, and is connected to a mixing injection pipe 5 outside the boiler shell 1 through the feed pipe 4. After the pure water in the pure water tank 7 is pumped into the mixing injection pipe 5 through the jet pump 10, the electrolyte raw material to be added is added into the mixing injection pipe 5 by the push feeder 8 on the feeding port, and the pure water and the electrolyte are evenly mixed by the mixing action of the water wheel mixer 9, and then pumped into the feed pipe 4 through the mixing injection pipe 5, and then the electrolyte water is evenly sprayed into the water of the electrode boiler by a plurality of nozzles 6 evenly arranged in a circular array on the annular feeding pipe 3 to increase the electrolyte concentration.

After the pure water is pumped into the mixing injection pipe 5 and passes through the connecting pipe section 901, the rotating water wheel 902 is driven to drive the rotating agitator 903 to rotate to mix the electrolyte raw materials added by the push feeder 8 with the pure water to form electrolyte water, thereby increasing the uniformity of the electrolyte and enabling it to be integrated into the boiler water more quickly.

The telescopic end of the propulsion cylinder 803 is extended and retracted to drive the piston of the syringe 801 to move, thereby pushing the material in the syringe 801 into the pure water.
